I'll use a number of conventions you should know about in this book.
For example, menu items are separated with an→ like this: File→ New→ Project. To make them stand out, new lines of
code will be displayed highlighted when they're added. Example code is
often presented out of context; instead of developing an entire class,
only the relevant block of code is presented. Most examples will include
the necessary import statements for Commons-relevant classes, and other
import
statements will be implied. When
code is omitted or implied, it will be represented by ellipses:
import org.apache.commons.digester.Digester; ... Digester digester = new Digester( ); digester.doSomething( );
In addition, the following typographical conventions are also used in this book:
Indicates new terms, URLs, email addresses, filenames, file extensions, pathnames, directories, and Unix utilities.
Constant width
Indicates commands, options, switches, variables, types, classes, namespaces, methods, modules, properties, parameters, values, objects, events, event handlers, and XML tags.
Constant width italic
Shows text that should be replaced with user-supplied values.
Constant width
bold
Highlights important text within code examples.
